Does anybody know what it was? And was Uncle Leo her brother?

Yes, Uncle Leo was Helen's sister. I don't think they ever said what her Maiden name, or Uncle Leo's last name was.

This is just a guess, but maybe it was Levine.

Oh yeah, didn't someone mispronounce it as Levigne (LE-VEEN)?

I remember an Artie Levine..who was that? Jerry's cousin?

Yes, Jerry introduced Elaine to his cousin Artie Le-veen. And Artie corrected Jerry and said his last name was Le-Vine.

Helen's maiden/Uncle Leo's last name were not revealed.

>>>For all it's worth, Uncle Leo's last name was never revealed either. All we know is that he's a brother of Jerry's mom ("The Kiss Hello"). But since we don't know her maiden name we're in the dark about Leo's surname. In the aforementioned "The Package," he signed for Jerry's delivery as "Uncle Leo." So even he refers to himself as such. (So in a single episode its writer, Jennifer Crittenden, puts a little spotlight on the fact that we don't know the complete names of these two recurring characters, having some fun with it in the process.) And in another episode, "The Bookstore," Kramer - not realizing at first to whom Jerry is referring by just "Leo" - mentions to him that he forgot his first name, "Uncle."<<<

I have an alternate take on "The Package". After hearing Newman's reacation to seeing who signed for the package and seeing//saying Uncle Leo, I thought it would be very weird for Leo to identify himself as Uncle to the outside world, especially since his pride and joy seems to be his son Jeffrey rather than his nephew Jerry. So my thought is that Newman sees whatever name Leo signs, such as Leo Dingleberry, and just translates it into the name everyone knows Leo by, Uncle Leo.

This of course assumes that Newman would know Leo's actual last name when seeing it on the form. :crazy:

Possibly....
I think Kramer's response/dub-take on the Uncle thing makes the emphasizes to support pizzabagel's take.

perhaps, but Cosmo was so out of it he probably really though Leo's first name was Uncle. Need I remind you of "Lilly"?

Yes please :confused:

LOL

Kramer thought Susan's name was Lilly. When she died he even said, "poor Lilly".

HAHA I remember that...

He also called Elaine "Carrol" and George "Mike," but that was after he hit his head, or I think Joe Devola kicked him.
